Play: Death of a Salesman

I just read Arthur Miller's Death of A Salesman. A powerful play! I was not prepared for the shocking climax. Reminds me of two other plays I read recently. I'm surprised to note that these great plays are all about a seemingly normal family with two grown sons, and the story takes place within one or two days. By the end of the play, we learn some unspeakable sad stories about the family. Are all the American families so tragic, and all family conflicts rooted so deeply in the past?

I'm beginning to enjoy plays. A good play tells a complex and big story in a short time. It shows the genius of the playwright. Nowadays there are movies, but movie scripts are different from plays. In a movie, the story telling doesn't have to be so focused, and many technological devices can be used, but the result is usually less intense. I'd like to read more plays.
